Abstract
A printing machine, such as a typewriter, printer, etc., including a platen having wound thereon a sheet for printing characters and symbols thereon and provided with an automatic sheet feeding apparatus including a cassette containing a plurality of sheets automatically fed to the platen. The cassette can be inserted into or withdrawn from the sheet feeding apparatus through an opening in the front of the sheet feeding apparatus. The sheet feeding apparatus enables a sheet to be selectively fed manually, if desired, besides enabling sheets to be fed automatically from the cassette. The sheet feeding apparatus enables a paper bail to be mechanically operated in conjunction with its operation of automatically feeding sheets to the platen.
